The easier it is the more people will use it, so I see this as a big win. They have a good repuation (well most of) and giving people access in a uncomplicated manner can just be good to support the global acceptance rate
Are you referring to PayPal as a company? Unfortunately this company has no single reputation when talking about companies about to venture into cryptocurrency, this company had done evil to her customers including myself about my pending transactions. Their support service is the worst among all others. MasterCard is what am happy for coming into the cryptocurrency space because they actually have their reputation built solidly and their presence will help grow global adoption.
